Technical Field

[0001] The utility model relates to the technical field of building materials, and more specifically, to a fireproof building block. Background Art

[0002] Before pouring concrete blocks, if bent and shaped steel bars are embedded in the mold, the formed concrete blocks can have higher structural strength. In order to give the blocks a higher fire resistance level, a fireproof layer of a certain thickness is usually arranged on the outer side of the blocks to achieve a higher fire resistance effect.

[0003] Since the fireproof layer and the concrete block are two different materials, when the two are connected, they are usually connected only by the bonding force of the fireproof layer before solidification. The connection has limitations. The fireproof layer is easy to fall off after being baked at high temperature, which seriously affects the fireproof performance and the overall effect is not good. Therefore, the utility model proposes a fireproof block. Utility Model Content

[0006] The utility model is further configured as follows: the connecting piece comprises a pipe fitting sleeved on the first reinforcing steel bar, a connecting piece buried inside the fireproof layer, and a connecting column is provided between the connecting piece and the pipe fitting.

[0007] The utility model is further configured as follows: penetration holes are arranged on the connecting sheet.

[0008] The utility model is further configured as follows: a side hole is opened on the pipe fitting, and a locking spring piece is arranged in the side hole, with one end connected to the pipe fitting and the other end abutting against the first reinforcing steel bar.
